I'd like to install the new version of XAMPP, but keep the old version as well, since the PHP and MySQL components of the old version correspond more closely to one of the web servers I use.
Here's the method I'm planning:
Move old version to /opt/lampp_1.4.9a
Put new version in /opt/lampp_1.5.5a
Create a symlink /opt/lampp that points to one of above directories.
Then I can switch between the versions as follows:
# /opt/lampp/lampp stop
Change the symlink /opt/lampp to point to the other directory.
# /opt//lampp/lampp start
Do you see any problem with this?
